HYDRocAnBoN Moron.

Original. application led September To all wlwm may concern Be it knownthat I- JESSE G ViNesN'ig a citizen of the Unitedtates, and residing atDetroit,county of Wayne, State of Michian, have invented certain new anduseful mprovements inHydroc'arbon Motors, of which the followin is Aaspecification.

The=present app 'cation which is a divisionv Iof-:myi prior 4application190,241, filed September 7,` 1917, relates to hydrocarbon motorsandinore particularly tothe mounting of the pump and generator and thedrive therefor. the invention rare to locate the'pump in an ,-accessibleposition such as at the front of the 'motor-gl to provide a` simple-'anddependable drive'for the pump; to locate the pump so that the drive forthe generator alsoiserves-to; operate the pump kand to provide an easilyVmanipulated adjustment to take up thev slackiin the chain driveoperating the Tpum and' generator shaft'.l Other objects and eatures ofnovelty will be ap- .parent from the description taken in con- -nectionwith thedrawings, in which Fi 1 is a front elevation of a portion of ahy ocarbon motor embodying the present invention; l

Fig. 2 is a similar: view with the front cover and pump removed;

Fig. 3 is a side elevation of a portion of the motor, certain partsbeing shown in section; and x Fig. 4 is a sectional elevation takensubstantially on the line 4-4 of Fi ure 3.

Referring to the drawings t e reference numeral 10 indicates a housingVarranged at the front of the motor M and enclosing a chain drive whichconnects the crank, cam, and pump or generator shafts. The front side orcover 11 of this housing is removably secured to the motor in anydesired manner, as by means of cap screws 11" and is formed with anaperture 12`through which communication is had with the crank case 13 ofa pump, this crank case being secured over the opening Y12 in a suitablemanner, as by means of the cap screws 13. In the form of the inventionillustrated, this pump i's'of The principal objects of end of the strap65 and extending through a '7, 1917, Serial No. 190,241. Divided andthis application filed July 17, 1919. Serial No. 311,472.

A generator'G is mounted atthe opposite side of the housing 10. As shownthis gen-- erator has its-casing or frame 63 rotatively Vsupported on .acradle 64 carried by the .crank case'Cof the motor.

have their opposite endspivotally connected tothe cradle as by meansofthebolts 67 and 68 respectively. The adjacent ends lof the the straps65 and 66'are connected forl adjustment by means of a bolt 69 pivotedtothe lug70 on the adjacent end'of the strap 66, whereby the adjacent'ends of the straps are adapted to be pulled toward each other-,andthereby clamp tha-generator `against the cradle-{$4} End .plate -72 ofthe-generator 'which is rigidly secured to the casing 63 is providedwithl a sleeve 78 Whicliprojects into the housing 10 at the front endfofthe motor. 'Thissleeve consists of a cylindrical portion 74 which isconcentric with the generator shaft 75 and is mounted for lrotativeadjustment in the circular aperture o'r bearing 76 of the wall 77 of thehousing. The sleeve also has a cylindrical portion 78 Within thehousing, the axis of which is eccentric to the axis of the shaft 75.Mounted on the sleeve is the chain sprocket 16 which is connected torevolve with the shaft 75 as by means of a. coupling 79. From theforegoing it is obvious, when the generator casing is adjustedrotatively, the sleeve 78 will A'be turned thereby moving the axis ofthe sprocket 16 laterally, thus taking up the slack in the chain aroundthe sprocket.

The crankcas'e 13 of the pump is formed with a hollow boss 84, the boreof which is `aligned with the shaft 75, which projects diate thecoupling 79 and the endof the;

shaft, the latter carries an eccentric 87 which by means of theeccentric rod 88 operates the piston of the pump. Obviously other meansmight be employed for operating the pump from the shaft 75.` f l Thesprocket 16 is actuated from the crunk shaft 15 of the motor, the chain20 passing around the sprocket1 16-thesprocket 14 on the crank shaft anda sprocket 19 secured to the cam shaft.

In order to tightenthe chain the straps and 66 are` ,loosened So thatthe generator casing may'be'rotatively adjusted by means of a spannerWrench engaging in the holes 91 of the casing. As the eccentric portion78 of the sleeve is directly connected with the'generator casing, thiseccentric portion will be rotated, thereby shifting the axis of thechain sprocket 16 laterally and tightening the chain. Ater the chain hasbeen tightened to the desired degree, the generavtor ma `beclampedagainst this cradle so as `to hol the sleeve in this adjusted position.The spring 86 at the end of the shaft acts to 'hold the parts of thecoupling 79 in operative positions.

It "will fhe` observed, according to the present invention, the pump isdisposed at thefront of the motor Where it is easily accessible, and maybedisrnounted without disturbing its drive, or the drive of other partsof the mechanism. Furthermore means is provided for adjusting thetension of the 'chain-I which drives the pump.

Although a specific embodiment of the invention has been described indetail, it is to be understood that' itis not thus limited. but includesmodifications land 'changes which come Within the Scope of the appendedclaims..
